Cara Menyimpan Poros PTO Selama Musim Dingin Tanpa Merusaknya

Remove the shaft from the tractor and implement and clean all external surfaces with a stiff brush and water, removing all soil, crop debris, and any chemical residue from agrochemical application operations. Pay particular attention to the telescoping joint overlap area — soil packed in this zone holds moisture against the tube surface throughout winter and produces heavy corrosion that prevents telescoping the following spring. Allow the shaft to dry completely before proceeding.

Check each cross joint for play in all four trunnion directions. Any detectable play indicates Stage 2 wear — replace the cross joint before storage so it is ready at the start of the new season rather than requiring a mid-season repair. Grease all cross joint nipples until fresh grease is visible at each seal. Cross joints that enter winter with fresh grease in the bearing cups show dramatically less corrosion on the needle rollers and tracks after three months of cold storage than ungreased joints.

Extend the shaft to its maximum length, clean the inner tube surface thoroughly, and apply a generous coating of multipurpose grease to the inner tube’s external profile over the full telescoping travel range. Retract the shaft to its working length and grease through the telescoping grease nipple if present. The grease prevents moisture from entering the telescoping interface and prevents the internal profile (lemon, triangular, or rectangular bore) from rusting to the point of seizing during storage.

Inspect the plastic safety shield for cracks, brittleness, and missing sections. Cold winter temperatures cause already-degraded plastic to become more brittle — a shield that was cracked at the end of the season will likely shatter during the first cold-morning startup the following spring. Replace damaged shield sections before storage rather than discovering the damage when you need the shaft urgently. Apply a light coating of silicone spray to the shield’s outer surface to protect against UV degradation during storage.

Spray or brush a rust inhibitor oil onto all bare metal surfaces — shaft tube exteriors, yoke ears, any chrome or polished surfaces on the stub shafts. Light machine oil or spray lubricant is adequate for interior storage. For shafts stored outdoors or in unheated open sheds, use a heavier rust-inhibiting coating or wrap the shaft in a moisture-barrier sleeve.

Store the shaft horizontally on a rack or hung from hooks at both ends — never stand it vertically on one end as this allows grease to migrate out of the lower cross joint bearing cups and concentrate at the lower seal. Store in a dry, covered location if possible. Shafts stored in open conditions through freezing temperatures develop seal damage from ice formation in the bearing cup seals over repeated freeze-thaw cycles.
